June 7th. Chris Flexen threw a five-hit shutout in his Double-A debut for the Binghamton Rumble Ponies, striking out six and not walking a batter. He starred for Binghamton as the Rumble Ponies won the second game of a doubleheader, 3-0, against the Richmond Flying Squirrels after losing the first game.
Flexen needed only 83 pitches to complete his seven-inning shutout. His pitches ranged from 74 mph (curveball) to 94 mph (four-seam fastball), with 63 of his pitches being strikes. His fastball had good movement low in the strike zone, resulting in 11 ground ball outs, with very few balls being hit hard against him.
Flexen, a 14th-round selection in the 2012 amateur draft, entered the season as the 22nd prospect in the Mets organization, according to Baseball America. His repertoire agains the Flying Squirrels included a fastball, slider, and curve. Tonight was only his fourth start of the season, as he had been rehabbing a knee injury for the first six weeks of the season.
Before his promotion to Binghamton, Flexen had started three games in a rehab stint at St. Lucie, going 0-0 with a 2.13 E.R.A. Flexen spent all of 2016 in St. Lucie, winning 10 games and striking out 95 hitters in 125 innings.
